Note: This page follows a columnar organization: Basic Facts and Categories to the left, and Projects to the right.
The Dashboard will initialize a random choice of Category and Project in the Category Report and Project Report areas,
respectively. Use the selection and search fields to select a category or a project that you want to generate a Report
for.

Note: We study the distribution of Wikidata usage across the semantic categories to
determine which client projects use Wikidata in a similar way. In this graph, each project points towards the one
most similar to it. The selected projects has a different color. The results are relevant only in the context
of the current selection: the selected project + its 20 nearest semantic neighboors.

Here you can make selections of client projects and semantic categories to learn about Wikidata
usage across them.Note: You can search and add projects into the Search projects field by
using (a) project names (e.g. enwiki, dewiki, sawikiquote, and similar or (b) by using
project types that start with "_" (underscore, e.g. _Wikipedia, _Wikisource, _Commons, and
similar; try typing anything into the Select projects field that starts with an underscore). Please note that by selecting
a project type (again: _Wikipedia, _Wikiquote, and similar) you are selecting all client
projects of the respective type, and that's potentially a lot of data. The Dashboard will pick unique
projects from whatever you have inserted into the Search projects field. The selection of projects will be intesected
with the selection of semantic categories from the Select categories field, and the obtained results will refer only
to the Wikidata items from the current selection of client projects and semantic categories.
In other words: disjunction operates inside the two search fields, while conjunction operates
across the two search fields.Note: The Dashboard will initialize a choice of three project types
(Wikipedia, Wikinews, and Wiktionary) and a random choice of six semantic categories. All charts will present at
most 25 top projects in respect to the Wikidata usage and relative to the current selection; however, complete
selection data sets are available for download (.csv) beneath each chart.

WDCM Usage Dashboard

Description

Introduction

This Dashboard is a part of the Wikidata Concepts Monitor (WDMC). The WDCM system provides analytics on Wikidata usage
across the Wikimedia sister projects. The WDCM Usage Dashboard focuses on providing the detailed statistics on Wikidata usage in particular sister projects or
the selected subsets of them. Three pages that present analytical results in this Dashboard receive a description here: (1) Usage, (2) Tabs/Crosstabs,
and (3) Tables. But first, definitions.

Definitions

N.B. The current Wikidata item usage statistic definition is the count of the number of pages in a particular client project
where the respective Wikidata item is used. Thus, the current definition ignores the usage aspects completely. This definition is motivated by the currently
present constraints in Wikidata usage tracking across the client projects
(see Wikibase/Schema/wbc entity usage).
With more mature Wikidata usage tracking systems, the definition will become a subject
of change. The term Wikidata usage volume is reserved for total Wikidata usage (i.e. the sum of usage statistics) in a particular
client project, group of client projects, or semantic categories. By a Wikidata semantic category we mean a selection of Wikidata items that is
that is operationally defined by a respective SPARQL query, returning a selection of items that intuitivelly match a human, natural semantic category.
The structure of Wikidata does not necessarily match any intuitive human semantics. In WDCM, an effort is made to select the semantic categories so to match
the intuitive, everyday semantics as much as possible, in order to assist anyone involved in analytical work with this system. However, the choice of semantic
categories in WDCM is not necessarily exhaustive (i.e. they do not necessarily cover all Wikidata items), neither the categories are necessarily
mutually exclusive. The Wikidata ontology is very complex and a product of work of many people, so there is an optimization price to be paid in every attempt to
adapt or simplify its present structure to the needs of a statistical analytical system such as WDCM. The current set of WDCM semantic categories is thus not
normative in any sense and a subject of change in any moment, depending upon the analytical needs of the community.

Usage

The Usage tab provides elementary statistics on Wikidata usage across the semantic categories (left column) and sister projects
(right column).To the left, we first encounter a general overview of Basic Facts: the number of Wikidata items that are encompassed by the current WDCM taxonomy (in effect,
this is the number of items that are encompassed by all WDCM analyses), the number of sister projects that have client-side Wikidata usage tracking enabled (currently,
that means that the Wikibase/Schema/wbc entity usage) is present there),
the number of semantic categories in the current version of the WDCM Taxonomy, and the number of different sister project types (e.g. Wikipedia, Wikinews, etc).
The Category Report subsection allows you to select a specific semantic category and generate two charts beneath the selection: (a) the category top 30 projects chart, and
(b) the category top 30 Wikidata items chart. The first chart will display 30 sister projects that use Wikidata items from this semantic category the most, with the usage data
represented on the horizontal axis, and the project labels on the vertical axis. The percentages next to the data points in this chart refer to the proportion of total category usage
that takes place in the respective project. The next chart will display the 30 most popular items from the selected semantic category: item usage is again placed on the horizontal axis,
item labels are on the vertical axis, and item IDs are placed next to the data points themselves.
The Categories General Overview subsection is static and allows no selection; it introduces two concise overviews of Wikidata usage across the semantic categories of
Wikidata items. The Wikidata Usage per Semantic Cateory chart provides semantic categories on the vertical and item usage statistics on the horizontal axis; the percentages
tells us about the proportion of total Wikidata usage that the respective semantic category carries. Beneath, the Wikidata item usage per semantic category in each project type
provides a cross-tabulation of semantic categories vs. sister project types. The categories are color-coded and represented on the horizontal axes, while each chart represents one project
type. The usage scale, represented on the vertical axes, is logarithmic to ease the comparison and enable practical data visualization.
To the right, an opportunity to inspect Wikidata usage in a single Wikimedia project is provided. The Project Report section allows you to select a single Wikimedia
project and obtain results on it. The first section that will be generated upon making a selection provides a concise narrative summary of Wikidata usage in the selected project alongside
a chart presenting an overview of Wikidata usage per semantic category. The next chart, Wikidata usage rank, show the rank position of the selected project among other sister projects
in respect to the Wikidata usage volume. Beneath, a more complex structure, Semantic Neighbourhood, is given. In this network, or a directed graph if you prefere, each project points
towards the one most similar to it. The selected projects has a different color. The results are relevant only in the context of the current selection: the selected project and its 20 nearest
semantic neighboors only are presented. Once again: each project points to the one which utilizes Wikidata in a way most similar to it. The top 30 Wikidata items chart presents the top 30
Wikidata items in the selected project: item labels are given on the vertical axis, Wikidata usage on the horizontal axis, and the item IDs are labeled close to the data points themselves.

Tabs/Crosstabs

Here we have the most direct opportunity to study the Wikidata usage statistics across the sister projects. A selection of projects and semantic categories will be intersected and only results in
the scope of the intersection will be returned. The charts should be self-explanatory: the usage statistic is always represented by the vertical axis, while the horizontal axis and sub-panels play
various roles in the context of whether a category vs project or a category vs project type crosstabulation is provided. Data points are labeled in million (M) or thousand (K) pages (see Wikidata usage)
definition above). While charts can display a limited number of data points only, relative to the size of the selection, each of them is accompanied by a Data (csv) button that will initiate a
download of the full respective data set as a comma separated file.

Tables

The section presents searchable and sortable tables and crosstabulations with self-explanatory semantics. Access full WDCM usage datasets from here.
